# Smart Model Routing: The New Trend Cutting AI Costs Companies are turning to intelligent routers to optimize their AI spending. - **Source:** [The Pragmatic Engineer](https://blog.pragmaticengineer.com) - **Published:** 2026-07-02 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/1fd448e0-2e65-4f58-b053-4a320d96c1ee ## Revolution in AI Costs Companies are adopting smart routing systems to optimize the 10-20x cost differences in AI model tokens. These systems automatically select task-appropriate models, delivering significant savings. They offer a new solution for firms looking to reduce AI expenses in engineering departments. ## Market Game Changers Tools like Factory Router, Not Diamond, and Vercel AI promise 20-30% cost savings. Platforms like OpenRouter use Not Diamond's auto-routing technology under the hood. Solutions like Prism and Model Router, optimized for coding tasks, are also gaining attention. ## Enterprise Demand Surge According to Factory AI CEO Matan Grinberg, demand from large companies, especially banks, is at record levels. Open-source models reportedly deliver sufficient performance for 60% of coding tasks. The last six months have seen a noticeable increase in open model usage. ## Integrated Solutions Rising Platforms like Cursor and GitHub Copilot offer built-in auto-model selection features. However, Copilot's Pro plans being limited to older model versions has caused dissatisfaction among developers. Solutions like LiteLLM and Kilo Gateway offer more control. ## Routing Strategies Systems route 'hard' requests to premium models and 'easy' ones to open-source models to reduce costs. Tools like Weave router automate this distinction. Requestly.ai offers advanced configuration options balancing cost, latency, and availability. ## The Future Standard Smart routing features are expected to soon become standard across all AI providers. This cost-optimizing, performance-balancing technology appears poised to become essential, especially for large-scale enterprise users. ## Sources covering this story - https://blog.pragmaticengineer.com/the-pulse-a-new-trend-smart-model-routing/ — --- _Summary written by Brifing from the original reporting.
